MACHINE `FOR RULINC-r PAPER.

, Specification of Letters Patent No. 2,648, dated May 28, 1842.

with the accompanying drawings, forms a full and exact specifica-tion.

In said specification I have set forth the nature and Aprinciples of my invention, by

which it may he distinguished from others of like character, together with such parts or combinations of the same asI claim, and for which I solicit Letters Patent.

Figure l, of the drawings above mentioned represents a top view of my improved ruling machine. FigQ, is a side elevation and Fig. 3, is a central vertical and longitudinal section.

Two cylinders A, B, Figs. l, 2, 3, each of about one foot in diameter andcovered on their exterior circular surfaces with felting or smooth cloth `or other suitable material, are so arranged and supported on a proper framework C, that one half of one side of a sheet of paper isruled in passing around the one and the whole of the other side of it in passing around the other of said cylinders.

For convenience in description I shall consider that end of the machine at which the roller G is situated the front end and the opposite end the rear end,-and, as occasion may require, shall designate the several parts by the terms front and rear, according as they may be situated with respect to said ends.

The second cylinder B is elevated the length, or about the length of its diameter higher than the first, and is placed somewhat at, or aproper distance therefrom, so as to be nearly over the feeding apron, or so that a sheet of paper may reach and be brought into contact with the second cylinder immediately after it is liberated from the first cylinder. The feeding apron D is an endless band or cloth passing, and stretched tightly, and running over three rollers or cylinders E, F, G, the former of which rollers or cylinders is placed so as to bring the contiguous surfaces of the feeding apron and exterior cloth of the cylinder A into such close contact, that when the cylinder A is revolved, by the hand applied to a crank H, upon the shaft of said cylinder, or by any other suitable power, the apron will be moved by and with it. Another small cylinder or roller I, Fig. 8, is placed in contact with the outer surface of the cylinder A and just above the` roller E as seen in the drawing. A second and similar roller K is arranged on the top of the main cylinder A and a third roller L is also disposed in rear or on one side of the cylinder at a distance of a few inchestherefrom as seen in Fig. 3. Any suitable number of endless cords M tc. are passed around and drawn into close contact with the cylinder I, K, L and also with the exterior surface of the main cylinder A as seen in Fig. 3.

A roller N is placed somewhat in front of the upper part of the cylinder A in such manner that the upper edges of said roller and cylinder may be about in the same horizontal plane. -Tl1e cylinder B is driven or caused to revolve in an opposite direction to that of the cylinder A, by a crossed belt O passing over a pulley P on the shaft of the cylinder A,"a`nd also over a pulley Q on the shaft of the cylinder B, the diameterl of the pulley P being double or a little more than double that of the pulley Q-see Fig. l.

A roller R is arranged overthe cylinder B so that their surfaces may be nearly in contact and two other rollers S, T, are also disposed in front of said cylinder at a few inches distant therefrom, the diameters of the cylinder and rollers S being in the same or nearly the same horizontal plane, while the lower edge of the surface of the roller T is in a horizontal plane with the lower edge of the roller N. Lastly a roller U is placed at the rear part of the frame so that its upper edge shall be in or nearly in a horizontal plane with the upper edge of the cylinder B. Each of a series of endless cords V, V, V, Sac., passes around the cylinder B and the several rollers N, T, S, B, as follows. Commencing at the top of roller N each of the said cords extends to the lowest part of the cylinder B thence upward aboutthe front half of the cylinder B, thence` between the cylinder B and the roller R, thence upward and partly around the roller B and from thence to and around the front side of the roller S and thence downward around the front and lower parts of roller T thence to the lower part and around the rear side of roller N to the point of begin-ning, as seen in Fig. 3. Another series CIK of endless cords W, W, W, &c. extend around the cylinder B and the roller U, as seen in the drawings. The feeding apron passes over a board or table X Figs. 3, arranged at the front part of the framework, so that the sheets to be ruled are placed upon the apron directly over the board X.

Two series of ruling pens, such as are generally used are arranged as seen at Y, Z, the former resting upon the cylinder A and the latter upon the'cylinder B as seen in the drawings. Y

The operation of ruling paper may be thus explained. The second sheet of paper, laid upon the feeding apron, (and each succeeding one), is lapped half its width upon the one in advance of it. In this state the sheets pass around the rear side and over the top of the first cylinder A and are received from thence upon the cords V as they pass over the roller N, toward the cylinder B. During this process, the whole of the under surface of the rst sheet is ruled and only half the under surface of each succeeding one. The paper is next carried horizontally upon the cords V &c. from the top ofthe first to the bottom of the second cylinder` B, and is received between the cords V and the cylinder, which latter, (taking the sheet of paper as soon as it is liberated from the first cylinder), by its double velocity drawsthe sheet forward twice as fast as the one in rear, thus taking out its lap and that of each successive sheet before they reach the pins Z of the cylinder B, by which pens the whole of the opposite side Y of each sheet is wholly ruled. Thus the half yof one and the whole of the other side of each sheet (excepting 4the first) will be( ruled, so that when the sheets are folded into the quire form, three sides of each will be ruled. As the sheets leave the top of the upper cylinder B, they pass over the cords W and roller U and drop successively upon an inclined board a, placed in rear of the roller U, from which board they may be removed as occasion may require.

Having thus explained my invention I shall claim- The two cylinders A and B (arranged, so that the lowest edge or part of the upper, shall be situated at a distance from the upper edge o-f the lower cylinder equal or a little greater than the length of the sheets to be ruled, said length being taken in the direction in which the -sheets move, and said edges of said cylinders being in, or about in a horizontal plane; and so that the cylinder B shall have a velocity double that of the cylinder A,) in combination with the systems of rollers and cords, whereby Vthe sheets are received from an endless feeding apron upon which they are placed so as to lap over each other, and from thence are caused to pass around t-he first cylinder and vbe ruled thereon, upon one half of one of their sides, and from thence to pass around the second cylinder and be ruled over the whole of their opposite sides as before set forth, the whole being arranged and operating substantially in the manner described. In testimony that the foregoing is a true description of my said invention and improvements I have hereto set my signature this fourteenth day of March in the year eighteen hundred and forty two.
